Third, fourth and fifth grade friendly, this "ready to go" printable 6 week project isn't at all complicated. Simple for them, means simple for you! :) In addition to teaching all about vertebrates and invertebrates, it teaches a lot about expectations and following directions. Being completely editable allows you to tweak it to your specific needs and teaching style.
